This sky is something that we could see when the plane takes off and just penetrates the layer of clouds, above them strong light from sun and blue sky that for a moment we have to shut the eyes, just get to use to such intense light. It was few years ago when I flew last time but such moments are always in your memory. Beautifully done @xpilar, love how you used blue and purple to show the contrast between the part in light and shadow :)
